Notably + Visual Studio 2013, recent mingw with c++ threads and some OSX + fixes. + +* we now have mips and mips64 support! (courtesy of Jovan Zelincevic, + Jean Lee, user xiaoyur347 and others) + +* we now have aarch64 (aka arm64) support! (contributed by Riku + Voipio) + +* there's now support for ppc64-le (by Raphael Moreira Zinsly and + Adhemerval Zanella) + +* there's now some support of uclibc (contributed by user xiaoyur347) + +* google/ headers will now give you deprecation warning. They are + deprecated since 2.0 + +* there's now new api: tc_malloc_skip_new_handler (ported from chromium + fork) + +* issue-557: added support for dumping heap profile via signal (by + Jean Lee) + +* issue-567: Petr Hosek contributed SysAllocator support for windows + +* Joonsoo Kim contributed several speedups for central freelist code + +* TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES environment variable now works + +* configure scripts are now using AM_MAINTAINER_MODE. It'll only + affect folks who modify source from .tar.gz and want automake to + automatically rebuild Makefile-s. See automake documentation for + that. + +* issue-586: detect main executable even if PIE is active (based on + patch by user themastermind1). Notably, it fixes profiler use with + ruby. + +* there is now support for switching backtrace capturing method at + runtime (via TCMALLOC_STACKTRACE_METHOD and + TCMALLOC_STACKTRACE_METHOD_VERBOSE environment variables) + +* there is new backtrace capturing method using -finstrument-functions + prologues contributed by user xiaoyur347 + +* few cases of crashes/deadlocks in profiler were addressed. See + (famous) issue-66, issue-547 and issue-579. + +* issue-464 (memory corruption in debugalloc's realloc after + memallign) is now fixed + +* tcmalloc is now able to release memory back to OS on windows + (issue-489). The code was ported from chromium fork (by a number of + authors). + +* Together with issue-489 we ported chromium's "aggressive decommit" + mode. In this mode (settable via malloc extension and via + environment variable TCMALLOC_AGGRESSIVE_DECOMMIT), free pages are + returned back to OS immediately. + +* MallocExtension::instance() is now faster (based on patch by + Adhemerval Zanella) + +* issue-610 (hangs on windows in multibyte locales) is now fixed + +The following people helped with ideas or patches (based on git log, +some contributions purely in bugtracker might be missing): Andrew +C.
